Certification fails on new identities
```bash
silkaj cert kimamila --gtest
No matching identity
```
fails because `kimamila` id is not in the network.
Commenting `wot.py` make it works:
```bash
# Check that the id is present on the network
if (certified_pubkey is NO_MATCHING_ID):
message_exit(NO_MATCHING_ID)
```
